A six-month trial has been introduced for digital stamps. These stamps have limited use, applicable only to basic domestic mail.

This type of mail includes items such as letters, postcards, and printed paper in an envelope. The trial is being conducted by SingPost.

Further details about the digital stamp trial can be found through the source. The limited scope of the trial suggests it is an initial test of the digital stamp system, with its use restricted to specific types of domestic mail.
